Background: In our institution, the Philippine Heart Center, there is an increasing number of Filipinos with moderate ischemic mitral regurgitation and the optimal surgical management for these patients remains controversial. Likewise, the benefits of CABG alone and CABG with mitral valve surgery for this subset of patients remain to be defined. This study will provide our institution data comparing CABG alone and CABG with mitral valve surgery. This study aims to provide our surgeons a basis for their preference to perform CABG alone or CABG with mitral valve surgery for patients with moderate ischemic mitral regurgitation.
Methods: We conducted a 1-year prospective cohort study of patients who were admitted as cases of moderate ischemic MR undergoing CABG alone or CABG with Mitral Valve Surgery. Pre-operative data were recorded including patients' profile and echocardiography findings. Intraoperative data were likewise recorded including the procedure done, intraoperative transesophageal echocardiography findings and bypass time. Post-operative morbidity and mortality rates were recorded. Patients were followed up at the OPD. Follow-up 2D echocardiography were recorded at 2 months post-op. Statistical analysis was applied to data gathered.
Results: Analysis of data showed Group B has a 1.28x risk of developing an outcome including morbidities, mortality and residual MR. Though insignificant with P Value of 0.583.
Conclusion: CABG Alone is comparable with CABG with Mitral Valve Surgery in patients with moderate ischemic MR in terms of outcomes
